I’ve had 2 ENTs “look” at it in the past year, one of whole is a head and neck cancer specialist. Both said they couldn’t see it but they could feel it. Neither was concerned. I was told there is nothing to biopsy and the cancer specialist said it was not hard enough to be cancer. The mouth issue has been unchanged for over a year however in the last couple months I’ve developed a neck lump on the same side as the tongue issue. Pretty scary but I had a negative neck ultrasound about a month ago. I’m not totally convinced it didn’t miss something and think I’m going to try to get back into the ENT for further investigation...the ultrasound was not ordered by the ENT; have not seen the ENT in over 6 months.
